Topic: Help needed.. MapPos to ScreenPos

Hello, it's me... My POI system is working, but I'd like to im plement a feature, that allows the user to move the POIs.
For this, I have to convert a xy position on the map, to a xy postion on my screen. How can I do so?
Thanks!

In src/game/client/render.cpp, there is a function MapscreenToWorld that does the opposite of what you want. You just have to look how it's implemented and reverse the code.
